The c.259G>A (p.A87T) alteration is located in exon 3 (coding exon 2) of the ZNF704 gene. This alteration results from a G to A substitution at nucleotide position 259, causing the alanine (A) at amino acid position 87 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
